heterocyst function and - heterocysts fix nitrogen
where is it found - found in cyanobacteria, particularly Anabaena
- Prokaryotes
characteristics of - Oxygenic photosynthetic (in thylakoids) bacteria
cyanobacteria - Unicellular or filamentous
- Some fix nitrogen in heterocysts
what are the 3 domains of archaea, eukarya, bacteria
life
- eukaryotes
- photosynthetic
characteristics of algae - unicellular or multicellular
- no significant tissue differentiation
- live in lakes, ponds, rivers, oceans
- eukaryotes
- unicellular
characteristics of
- non-photosynthetic except Euglena
protozoa
- contain food vacuole, contractile vacuole,
macronucleus and micronucleus
what domain do protozoa eukarya
belong to
, what domain do algae eukarya
belong to
what are the two stages - cysts: dormant
protozoa? which is - trophozoites: active
active/dormant?
- mastigophora
4 classes of prokarya - sarcodina
depending on motility - ciliophoran
- sporozoans
what should you do first if tell the TA!
you break glassware in the
lab
Indicator of phenol red
glucose/lactose
fermentation
Biochemical test: - tests for glucose/lactose fermentation
Glucose/lactose - indicator: phenol red
- tests for... - results:
- indicator positive = color changes from red to yellow
- result negative = remains red
Biochemical test: Methyl - tests for glucose fermentation + acidic end product
Red (MR-VP tube) - indicator: methyl red (pH indicator)
- tests for... - results:
- indicator positive = red, pH 4-5
- result negative = yellow
Biochemical test: Voges- - tests for neutral end product
Proskauer (MR-VP tube) - reagents: alpha-napthol + KOH
- tests for... - results:
- reagents positive = red ring on top
- result negative = no change
